API reference - Class DeviceExtractorBase

Notation used in Ruby API documentation

Module: db

Description: The base class for all device extractors.

This is an abstract base class for device extractors. See GenericDeviceExtractor for a generic class which you can reimplement to supply your own customized device extractor. In many cases using one of the preconfigured specific device extractors may be useful already and it's not required to implement a custom one. For an example about a preconfigured device extractor see DeviceExtractorMOS3Transistor.

This class cannot and should not be instantiated explicitly. Use one of the subclasses instead.

This class has been introduced in version 0.26.

Public constructors

Detailed description

_create

Signature: void _create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

_destroy

Signature: void _destroy

Description: Explicitly destroys the object

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

_destroyed?

Signature: [const] bool _destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

_is_const_object?

Signature: [const] bool _is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

_manage

Signature: void _manage

Description: Marks the object as managed by the script side.

After calling this method on an object, the script side will be responsible for the management of the object. This method may be called if an object is returned from a C++ function and the object is known not to be owned by any C++ instance. If necessary, the script side may delete the object if the script's reference is no longer required.

Usually it's not required to call this method. It has been introduced in version 0.24.

_unmanage

Signature: void _unmanage

Description: Marks the object as no longer owned by the script side.

Calling this method will make this object no longer owned by the script's memory management. Instead, the object must be managed in some other way. Usually this method may be called if it is known that some C++ object holds and manages this object. Technically speaking, this method will turn the script's reference into a weak reference. After the script engine decides to delete the reference, the object itself will still exist. If the object is not managed otherwise, memory leaks will occur.

Usually it's not required to call this method. It has been introduced in version 0.24.

create

Signature: void create

Description: Ensures the C++ object is created

Use of this method is deprecated. Use _create instead

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

destroy

Signature: void destroy

Description: Explicitly destroys the object

Use of this method is deprecated. Use _destroy instead

Explicitly destroys the object on C++ side if it was owned by the script interpreter. Subsequent access to this object will throw an exception. If the object is not owned by the script, this method will do nothing.

destroyed?

Signature: [const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

Use of this method is deprecated. Use _destroyed? instead

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

device_class

Signature: DeviceClass ptr device_class

Description: Gets the device class used during extraction

The attribute will hold the actual device class used in the device extraction. It is valid only after 'extract_devices'.

This method has been added in version 0.27.3.

each_error

Signature: [iter] NetlistDeviceExtractorError each_error

Description: Iterates over all errors collected in the device extractor.

each_layer_definition

Signature: [const,iter] NetlistDeviceExtractorLayerDefinition each_layer_definition

Description: Iterates over all layer definitions.

is_const_object?

Signature: [const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

Use of this method is deprecated. Use _is_const_object? instead

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

name

Signature: [const] string name

Description: Gets the name of the device extractor and the device class.

Python specific notes:
The object exposes a readable attribute 'name'. This is the getter.

name=

Signature: void name= (string name)

Description: Sets the name of the device extractor and the device class.

Python specific notes:
The object exposes a writable attribute 'name'. This is the setter.

new

Signature: [static] new DeviceExtractorBase ptr new

Description: Creates a new object of this class

Python specific notes:
This method is the default initializer of the object
